MediaShelf has modified ActiveFedora to support sharding of Fedora Repositories. This means that you can transparently run Hydra heads on a system sharded across any number of Fedora Repositories. Docs on how Fedora Sharding works and how to use it are in Fedora Sharding Documentation document.
These Benchmark tests are meant to assess when it is beneficial/necessary to shard your Fedora Repository and how much benefit there is to sharding.
Goal: Assess the maximum number of write requests Fedora can handle, assess effect of sharding on this limit.
For the test harness, we’re aiming for the simplest harness that causes a single Fedora to fall down on write requests
